Expanded Plastic Foam Construction Toy

ABSTRACT

The disclosed technology relates to a construction toy made of expanded plastic foam extrusions. These extrusions are assembled with or without fasteners into a wide variety of configurations and optionally the extrusions are cut safely to a desired size.

FIELD OF THE DISCLOSED TECHNOLOGY

The disclosed technology relates generally to building toys and more specifically to light weight toys made of expanded plastic foam such as polyethylene or polyurethane.

BACKGROUND

Children's blocks have forever been a source of creative play. Albert Einstein, Frank Lloyd Wright, Charles Eames, Buckminster Fuller and other thought leaders famously credit their childhood blocks as a valuable educational resource from their early youth. While playing with blocks is often an immersive experience, few sets of blocks allow for the construction of structures that are full size play sets. The risk of such a structure falling on a child has typically prevented this scale of immersive play set.

The logs or blocks are great for inside or outside play. While the playset is designed for the real world, a computer based playset for the computer world is one option. In this way, children can plan their designs on the computer, make them in the real world and play with them in either environment. Accordingly, there exists the need for building toys that allow for full size play sets without the risk of injury from falling pieces or injury from jumping off structures.

Accordingly, it is one objective of the disclosed technology to provide a toy building set having a hollow plastic extrusion log and the hollow plastic extrusion log comprising a front side and a backside. Also comprising a first end and a second end as well as topside and a bottom side. Each top and bottom side having a substantially flat planar surface and a plurality of apertures in the substantially flat planar surface and the apertures extending from an outer surface of the log to an inner hollow surface of the log.

The plurality of apertures extending the length of the top and bottom sides' substantially flat planar surface, wherein the log is stackable by aligning the bottom side of said log with an adjacent topside of a log to thereby construct the desired lightweight self-supporting structure. The log is made of expanded polyethylene foam.

It is a further objective of the disclosed technology to have toy building set with a hollow plastic extrusion log wherein the log front side is curved and the backside is a substantially flat planer surface having a plurality of apertures extending from the outer surface of the log to the inner hollow surface of the log. A plurality of apertures extends the length of the backside of said log.

Another advantage of the disclosed technology is a toy building set wherein at least two adjacent logs are removably attached to a connector. The connector is multidirectional thus enabling the adjacent log to be rotated toward a specific direction and configured to interchangeably attach to each log. Wherein, the log is stackable with adjacent logs and connectors are placed between and inside apertures of adjacent logs to thereby construct the desired lightweight self-supporting structure.

According to some embodiments, the toy building set where the connector is removably attached to at least two adjacent logs through the apertures of the logs. Also, wherein the connectors comprise a central planar disk having two opposite ends from central planar disk and opposite ends further comprise distal planar disks. The distal planar disks pass through the apertures and into the hollow area of the logs to form an interference fit in the apertures with the central disk remaining outside of the apertures of the logs. Thus, the connector remains removably attached to the logs until desired removal.

It is also an objective of the disclosed technology to provide a connector where the two opposite ends from a central planar disk comprises a shaft shaped as a straight line S. Also, wherein the distal planer disks have an oval shape and the plurality of apertures in the log are circle shapes and passing of the distal planer disk through an aperture requires pressure and angling the distal planar disk through the aperture such that the connector overlaps a portion of the distal planar disk with a portion of the hollow inside of the log and thus secured until desired removal.

The distal planer disks of the connector have an oval shape and the plurality of apertures in the log have a matching oval shape; and wherein passing of the distal planer disk through an aperture requires positioning the distal planar disk shape to match the aperture shape. After the planar disk is through said aperture the connector is turned ninety degrees around an axis perpendicular to the distal planar disk such that the connector overlaps a portion of the distal planar disk with a portion of the hollow inside of the log and thus secured until desired removal. The connector is made with injection molded plastic.

Pluralities of apertures of a log are at fixed measurable intervals to each other, and the interval apertures determine a length by counting the apertures. A log is sawed into a plurality of smaller logs when a cutting edge provides tension onto a log such that bubbles of the plastic extrusion burst as the cutting edge go through the log.

Another objective is to have a saw comprising support for a dull cutting edge for cutting a log, and the dull cutting edge provides tension such that when the cutting edge is passed through the log, bubbles of the plastic extrusion burst as the saw passes through the plastic extrusion. The cutting edge of the saw comprises one of the following: plastic, metal, string; or wire.

In another objective there is a miter having vertical miter protrusions for placement of the log and a perpendicular slot in the vertical miter protrusions for placement of the cutting edge of the saw. When the cutting edge and the log are very stable for cutting the log.

In a further objective, a log front side and back side are both curved or the front side and back side are substantially flat planer surfaces having a plurality of apertures extending from the outer surface of the log to the inner hollow surface of the log. The plurality of apertures extends the length of the backside and the front side of the log.

In yet another objective, two adjacent logs are removably attached by a U connector and a log is stackable with an adjacent log and a U connector is placed on a portion of at least one end of a log and an adjacent log. The U connector uses spring tension on the two adjacent logs and remains removably attached to the logs until desired removal. Alternatively, the U connector has two ends and the two ends of the U connector further comprise protrusion that face each other such that the two ends are placed in the hollow of two adjacent logs and the two protrusions are placed in the apertures of the two adjacent logs. The U connector utilizes spring tension on the two adjacent logs and remains removably attached to the logs until desired removal.

Advantageously, the log apertures are shaped as one of the following: circle; two slits forming a plus sign; center circle superimposed on two slits; an oval; or an ellipse.

In another objective, the toy building set further comprises a spike having a first end with a flat head and a second end with a bulbous detail. The bulbous detail of a spike passing through a log aperture or a plurality of log apertures to the hollow area of a log such that the bulbous detail of the spike forms an interference fit in the aperture of a log and said spike flat head is sized to remain outside of a log.

It is also an objective to have a toy building set also comprising a flat plate fastener having an elongated oval planar shape with a first end having a portal there through and a second end having a portal there through.

A spike is passed through a portal of the flat plate fastener and a log apertures to the hollow area of a log such that the bulbous detail of the spike forms an interference fit in the aperture of the log and the spike flat head is sized to remain outside of the portal of the flat plate connector and of the log. Two adjacent logs are thus connected with apertures not facing each other.

In yet another objective, a toy building set having a hollow plastic extrusion log and the hollow plastic extrusion log comprising; a front side and a back side; a first end and a second end; a top side and a bottom side; each top and bottom side having a plurality of apertures in the extending from an outer surface of the log to an inner hollow surface of the log. The log is stackable by aligning the bottom side of said log with adjacent topside of a log to thereby construct the desired lightweight self-supporting structure.

In another advantage, the toy building set further comprising a fabric having apertures to accept and attach the fabric to a log or plurality of logs.

Also advantageous is a method of using a toy building set to build play sets comprising the following steps. First, selecting a plurality of logs, each log comprising; a front side and a back side; a first end and a second end; a top side and a bottom side; each top and bottom side having a substantially flat planar surface and a plurality of apertures in the substantially flat planar surface. The apertures extend from an outer surface of the log to an inner hollow surface of the log and extending the length of the top and bottom sides' substantially flat planar surface.

Second, determining the length of the logs needed for building a toy structure and determining what logs need to be cut. Third, counting the number of apertures on the logs needing to be cut to determine where to cut the logs and sawing the logs to appropriate sizes. Then placing one of the pluralities of logs on the ground or on a support horizontally with on of the substantially flat planar surfaces facing the ground or support.

Placing a connector or plurality of connectors into the apertures of the log placed on the ground or support and determining which of the plurality of logs is a second log to be placed on top of the log already placed. Then placing the second log, wherein the second log is stackable on the log already place and connectors are between and inside apertures of adjacent apertures of the logs.

Another method continues with a plurality of adjacent logs and connectors are placed between and inside apertures of adjacent logs to thereby construct the desired lightweight self-supporting structure.

In a final objective, a method of using a toy building further comprising the following steps of selecting a log and determining the length of the log needed. Then placing a miter on a flat surface and counting the apertures of the log. Placing the log in the miter the correct distance from the end to cut the log and then placing a saw in a slot of the miter to accept the saw. Finally sawing the log.

Expanded polyethylene extrusions provide a lightweight, soft, structural material that can allow children to safely build play structures of their own imaginations that reach over their heads without concern of injury. The blown polyethylene hollow extrusions interlock with simple connector designs that allow a child to assemble log cabins, forts, castles, boats and other imaginative structures quickly and easily with no tools other than a saw, if desired.

According to an aspect of some embodiments, there is provided a log 100. Log 100 of FIG. 1 is a blown or expanded hollow extrusion of plastic. One option is a circular extrusion of plastic. Log 100 is an elongated and typically hollow cylinder 140 with flattened exterior planar sections or substantially flat planar surface 110. The substantially flat planar surfaces 110 being opposite one another on log 100. Log 100 in some embodiments, also having two sides 120, being the radius of a circle.

In some embodiments logs 100 are made of polyethylene foam. Some embodiments of log 100 have apertures 130. In some embodiments, apertures 130 pass through from the exterior of log 100 to an interior hollow 140 of log 100, located on the substantially flat planar surface 110. Flat planar surface 110 in some embodiments comprises one or more of the four sides of log 100 and flat section 110 is 25 percent to 100 percent of the widths of the side of log 100.

Although apertures 130 need not be at regular intervals, placement of apertures 130 at regular intervals facilitates measurement without the use of a measuring tool. The ability to measure without a measuring tool is convenient when a certain size of log 100 is required for a play set. The regular intervals of apertures 130 provide a consistently measured length obviating the need for a measuring tool.

In some embodiments, apertures 130 of log 100 extend the full length of log 100. In some embodiments, the apertures 130 of log 100 do not extend the full length of log 100, and a portion of flat planar surface 110 at the end of log 100 does not have apertures 130. Logs 100, in some embodiments, have no flat surface; however, do have apertures 130 at regular intervals (not shown).

The apertures 130 allow fixed, pivoted, and/or removable connections between two logs 100. The logs 100 are malleable such that they can be bent from a straight shape to an acute angle shape and held there by connection with other logs, connectors or fasteners.

The log's 100 planar sections 110 enable stacking of logs 100 such that logs 100 sit in a stable manner, one on top of the other, even without the aid of further connectors. One of many building options is to configure logs 100 in the same stacking configuration as one would associate with crisscrossed logs seen in log cabin construction.

Tied string or adhesive tape is also an option for connecting a plurality of logs 100. Connectors 200, (See FIGS. 10-13) in some embodiments, are injection molded plastic, removably attached to logs 100 through apertures 130. For safety reasons, connectors 200 need to pass the toy industry standard test geometries of the Small Part Test. Toy industry studies have established that a part that cannot be wholly contained in a truncated cylinder with a 1.7 inches diameter achieves the safety level to pass the above tests.

FIG. 2 illustrates a log 100 b according to some embodiments. Log 100 b is very similar to log 100; however, a third flat planar surface 110 b is added to allow fasteners to fasten the logs together in a greater variety of configurations. Furthermore, the third flat planar surface of FIG. 2c is smaller in area than the other two flat planar surfaces of FIG. 2 b.

FIG. 3 illustrates log 100 b now having apertures 130 c shaped differently than apertures 130. Similarly, FIG. 4 has log 100 d with apertures 130 d shaped as two slits forming a plus sign. While FIG. 5 has a log 100 e having apertures 130 e, with a center circle superimposed on two slits.

FIG. 6 shows log 100 f that in some embodiments has flat planar surfaces 115 f on front, back, top and bottom sides of log 100 f. In some embodiments, the apertures 130 f are on only on two opposing sides, and the remaining two sides of log 100 f have no apertures. In some embodiments, the apertures 130 f are on all sides of log 100 f.

Log 100 g of FIGS. 7 and 8 are similar to log 100 f except they are now bisected lengthwise. Log 100 g, having apertures 130 g on only one side is illustrated by FIG. 7. Log 100 g, having apertures 130 g on all sides, is illustrated by FIG. 8.

FIG. 9 shows log 100 h, having flat planar surface 110 h on three sides, similar to FIG. 2. FIG. 9 illustrates that, in some embodiments, flat planar surfaces 110 h on all three sides of log 100 h are the same dimension. In some embodiments, all three flat planar surfaces 110 are of different area width of the sides. In some embodiments, all three flat planar surfaces 110 h have apertures 130 h. The remaining side 135 h is curved.

FIGS. 10a, 10b and 10c all illustrate a male connector 200. A central planar disk 210 bisects each of the opposite ends 220. Ends 220 point in opposite directions, outward from the central planar disk 210, with each end designed to pass through an aperture 130 of a log or logs 100 and/or fastener portal 510 of fastener 500 and 500 a (See FIGS. 22 and 24). There are pluralities of apertures 130 along each log 100 where connectors 200, when placed, allow the axis of logs 100 to be angled relative to each other and not limited to right angle connections.

Now onto FIG. 11, which illustrates male connector 200 a, having a central planar disk 210 a that bisects each of the opposite ends 220 a and further comprising two distal planar disks 225 a. In some embodiments, male connector opposite ends 220 a comprise shaft 230 a, having the shape of an S with the center of the S being a straight line as seen in FIG. 11e . This S straight-line shape of 230 a requires less material than an X configuration, resulting in reduced cost of manufacturing.

FIG. 12 is similar to FIG. 11 having a connector 200 b with central planar disk 210 b that is now oval shaped and centrally bisected by each of the opposite ends 220 b. Connector 200 b further comprises distal oval shaped planar disks 225 b not centered to supports 230 b. FIG. 13 is similar to FIG. 11, now having a connector 200 c with oval shaped distal planar disks 225 c centered on supports 230 c.

The term “oval” as used in relation to the connectors means a shape with two radiuses with parallel sides. Also the term “ellipse”, as used herein, means a shape with a major and minor diameter and no radius.

One option to connect adjacent logs 100 with connectors 200 is illustrated in FIG. 14. FIG. 15 illustrates a distal planer disk connector 200 c and logs 100 c with oval shaped apertures 130 c. The passing of the connector 200 c through an aperture 130 c requires positioning the distal planar disk shape 225 c to match the aperture shape 130 c. Thus, after the planar disk 225 c is through the aperture 130 c the connector 200 c is turned ninety degrees around an axis perpendicular to the distal planar disk 225 c, such that the connector 200 c overlaps a portion of the distal planar disk 225 c with a portion of the hollow 140 inside of the log 100 c and is thus secured until desired removal.

Now onto FIGS. 16 and 17, U shaped connector 300 in some embodiments, has two ends 310 with protrusions 320 that face each other. In some embodiments, U shaped connector 300 has two ends 310 and no protrusions (not shown). The U connector 300 utilizes spring tension to hold two adjacent logs 100 together. Log 100 stacks on adjacent log 100.

FIG. 17 shows U connector 300 placed on a portion of at least one end 330 of log 100 h and adjacent log 100 h, such that ends 310 are placed in a hollow section 140 of two adjacent logs 100 h and the two facing protrusions 320 are placed in apertures 130 h. Whereby U connector 300 utilizes spring tension on the two adjacent logs 130 h and remains removably attached to logs 100 h until desired removal. Plastic and metal are two of many options from which U connector 300 are made.

A saw 400 and miter 450 as seen in FIGS. 18 to 21 is optionally used to cut any of logs 100 to size. Saw 400 has a narrow and planar plate 410, and in some embodiments, rounded backsides with wider handle 420. In some embodiments, a string or metal wire (not shown) is held between the ends of the wider handle 420 used to cut the logs 100. Saw 400 will cut log 100 by bursting the thousands of soft plastic bubbles. This method of cutting logs 100 results in minimal mess, i.e. such as saw dust with other materials, and also makes accidentally cutting a finger more difficult. In some embodiments, saw 400 will have teeth and in other embodiments, saw 400 will not have teeth but rather a non-sharp straight edge. The straight side of saw 400 is optionally made of plastic or metal.

FIGS. 19 to 21 illustrate miter 450. Miter 450 has a flat bottom 455 for resting log 100 for support. Miter 450 further comprises vertical portions 460 that each have a slot 475 through which saw 400 is aligned to help ensure saw 400 is perpendicular to log 100 during cutting. In some embodiments, log 100 is compressed when cut by the saw 400 guided by the miter 450. Other well-known miter systems may also be used.

Right angle fastener 500 is illustrated in FIG. 22. Right angle fasteners 500 are rigid and fixed in shape, having portals 510 with one portal 510 oriented at a 90-degree angle to the other. Portals 510 are used to pass connectors 200 there through as well as through an aperture 130 on a log 100. FIG. 23 illustrates two logs 100 attached at 90-degree angles to one another. That is, the planar section 110 of one log 100 is at a 90-degree angle to the planer section 110 of another log 100. The right angle fastener 500 attaches to an aperture 130 of each log 100 with a connector 200 passing through each log 100 and each portal 510 of right angle fastener 500.

FIG. 24 illustrates a flat fastener 500 a. Flat fastener 500 a has portals 510 a. When logs 100 are attached and apertures 130 are not facing each other, a flat fastener 500 a facilitates connection of logs 100, see FIGS. 26 and 27. Here the portals 510 a of flat fastener 500 a work when the logs 100 are aligned in the same two-dimensional plane to adjacent logs 100 to hold them in place together. Connectors 200 are one option to use; with connector 200 going through portal 510 a and apertures 130 of log 100.

In some embodiments, spike connector 600 (as seen in FIGS. 25 and 26) is used to go through apertures 130 and/or portals 510 a. Spike 600 having a flat head 610 and bulbous end 620. FIG. 25d showing the flat head 610 with a Phillips head portion.

A base 700 for use when logs 100 are supported on end by hollow 140 instead of a flat planar surface is illustrated by FIG. 28. Similarly, FIG. 29 illustrates a spike base 700 a. In some embodiments, spike section 710 a sticks into the ground and upper support section 720 a supports the hollow 140 of log 100. Spike base 700 a optionally includes at least one tether link 730 a for tying items to or to aid in removal from the ground.

FIGS. 30 and 31 illustrate corner connector 700 b for use in hollow 140 of logs 100. Providing even another way to build with the toy building set.

Panel 800 and corner panel connectors 850, as seen in FIGS. 32 to 35, are also interconnecting building structures in some embodiments of the current disclosed technology. Panels 800 having a bottom groove 810 and elongated protrusions 820 for interconnecting with each other, such that the protrusion 820 of one panel 800 fits into the groove 810 on the bottom side of another panel 800. Panels 800 further comprise side slots 830 for use with corner panel connectors 850.

Fabric or material elements (see FIG. 40) are optional additions to the toy building set of the currently disclosed technology. Fabric is optionally used for a roof, sail or any other play set building needs. There are a few options for the material element of the toy building set. A plastic foam extrusion on one side and material on other is one option for such a fabric. Another option is EVA material similar to a yoga mat. Finally, plastic foam extrusion woven inside of a fabric is an option. The fabric, in some embodiments, includes apertures of the same shape and size as log apertures 130, such that logs 100 and fabric are removably attached to each other and in some embodiments, using connector 200.

Using the devices of the disclosed technology, one can build a log cabin (FIGS. 36, 37 and 39) by stacking logs 100 at right angles using connectors 200 alone. Logs 100 are cut to size in order to fit as shown in the drawings. Other items such as castles and sailing ships can also be built as seen in FIGS. 38 and 40. Log cabins, forts, castles and boats are built quickly and easily assembled with no tools except optionally a saw 400.

In particular, in the sailing ship of FIG. 40 one can see long logs 100, which bend past short logs 100 internal to the ship causing the long logs to bend as they approach the bow of the ship. A combination of right angle fasteners 500, flat fasteners 500 a, and connectors 200 are used. Logs 100 and fasteners 200 are all that are needed if logs have apertures 130 on at least three sides. Flat fasteners 500, inserted between two logs 100 extending horizontally, support the cannons. The flat fastener 500 “sticks out” from logs 100 and is attached underneath the cannon, cut to length with saw 400 in some embodiments of the disclosed technology.

In some alternative embodiments, any other shape made from expanded plastic is used as the building blocks or logs 100. Furthermore, these building blocks or logs 100 can interlock directly without the use of connectors, in a range of ways. These ways include, but are not limited to; tongue and groove type interlocks.

In short, one can use the tools and embodiments described to connect logs 100 in multiple ways. The logs 100 have flat planar surfaces 110 with apertures 130 and hollow inner areas 140. The apertures 130 and inner areas 140 can be used to connect various straight, right-angled, and other connectors 200 while the log extrusions 100 themselves can be cut to any desired size. As such, one can create a next to limitless amount of varied creations.
